Water conservation design

A shortcut graphical technique for water conservation design for retrofit processes has also been provided. Two important graphs are provided to create initial water recycle networks for consideration in retrofit processes. Of particular importance is the usefulness... 

Boiler Design Issues Boiler design involves the interaction of many variables water-steam circulation, fuel characteristics, firing systems and heat input, and heat transfer. The furnace enclosure is one of the most critical components of a steam generator and must be conservatively designed to assure high boiler availability. The furnace... 

For example, if 12° is the wet bulb temperature not exceeded for 95% of the summer hours for the area, a conservative design air w et bulb inlet temperature would be 75°F. Then, for a 10°F approach, the design cold water temperature would be 85°F.

Retention time for both maximum oil rate and maximum water rate should be calculated, unless laboratory data indicates that it is unnecessary to take this conservative design... 

Note The KF factor is defaulted as a 200 value to derive a 1.0% water remainder specification in the treated oil.) You may find more accurate defaulted values of KF in your company s test. To date, however, this 200 value is proven to be a most accurate and conservative design value to achieve the 1.0% water specification. 

TkSep will give you a recommended and calculated tank diameter with calculated height for the oil residence time of your choice. As seen on the program screen in Fig. 4.14, a constant 1% treated-oil water content is maintained for all calculation runs. The program actually aims for 0.5% but displays 1% for a conservative design. 

Steam st ripping — This technique has long been used on sour water and process condensate in refineries. Steam stripping is also becoming more attractive in other industries as the demand for water conservation increases. In a number of process plants, high-quality process condensates are recovered, stripped, and reused. Effluent oil concentrations of less than 50 ppm are achievable in stripping columns but actual concentration depends on influent concentration, tower design and contaminant type. 

Originally, the water conservation areas were designed as buffer zones for waters destined for the southern Everglades and Everglades National Park. However, phosphorus impacts in these areas have shown signs of spreading to the pristine Everglades. Various...

Stanford CA. Soon later, he became assoeiated with the US Army Corps of Engineers, an association that he maintained for 64 years. His work with the Corps encompassed engineering and administrative activities in both rivers and harboms, flood control, power, irrigation, water conservation, and military construction. While at the Sacramento CA District, he was involved in the design, the construction, and the operation of these important projects as debris storage dams on the Yuba and American Rivers, and the Stockton Deep Water Channel, the Sacramento River Flood Control Project, Folsom Dam on the American River, and the Pine Flat, Isabella, and Big Dry Creek Dams in the San Joaquin Valley.
